Some issues however... Turbines operate much more efficiently at altitude,

more reliable, they are also more complex in certain ways (in spite of the
fundamental concept being simpler), and they are more finicky about proper
operation.

Can you explain why the efficiency of turbines is much higher at
altitude? What sort of efficiency are you talking about?
